A thermoplastic film 10 is a thermoplastic film comprising a light-emitting layer 11, wherein the light-emitting layer 11 comprises a thermoplastic resin and a light-emitting material that emits light by being irradiated with excitation light, and a change in yellowness of laminated glass obtained by bonding two sheets of clear glass in accordance with JIS R 3211 (1998) having a thickness of 2.5 mm with the thermoplastic film interposed therebetween after conducting a light resistance test for 2000 hours based on JIS R3205 2005 is 4 or less. The present invention provides a thermoplastic film comprising a light-emitting material, in which the emission intensity is unlikely to lower even when the thermoplastic film is exposed to ultraviolet rays for a long period of time.

Light-control panels including layered optical components are described in this application. An example of a light-control panel includes first and second glazing layers, first and second transitional layers extending between the first and second glazing layers that guide light emitted from a light source, and a third glazing layer extending between the first and second transitional layers through which light emitted from the light source is guided. The light-control panel also includes a light extraction layer extending between the third glazing layer and one of the first and second transitional layers that distributes light emitted from the light source. The first and second transitional layers have refractive indices that gradually decrease from a first value at surfaces proximate to the first and second glazing layers to a second value at surfaces proximate to the third glazing layer in the stack-up of the light-control panel.
